Answer:
0.7569, 0.5729,0.4371
Step-by-step explanation:
Given that the books are of only two types either non dash fiction or fiction.
Also probability of selecting a fiction = 0.87 = p
X - no of books fiction selected is binomial with p = 0.87 and n =2
(since each trial is independent of the other and there are only two trials)
a) the probability that both books are fiction=
b) Here n =4 with same p.
c) Prob atleast one is non dash fiction =
This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.
Answer:
i) $500 at 5% simple interest for two years. Interest = 550 - 500 = $50
ii) $500 at 3% compounded monthly for 2 years.
Interest = 530.88 - 500 = $30.88
Step-by-step explanation:
i) $500 at 5% simple interest for two years.
Initial amount, P = $ 500
Rate of interest, r = 0.05
Time in years, t = 2
Therefore Final amount A = P(1 + rt) = 500(1 + (0.05 2) ) = $550
Therefore Interest = 550 - 500 = $50
ii) $500 at 3% compounded monthly for 2 years
Initial or Principal Amount, P = $500
Rate of interest, r =0.03
number of conversions, m = 12
Time in years, t = 3
Therefore final amount, = $530.88
Therefore Interest = 530.88 - 500 = $30.88
